The base arm 12 extends upwardly fr om the base 10 into a slot 13 PIQVid Gd thEIQf OP- in the cylindricai housing. 20, ti'niretaihing the heusing 2G in its proper relative ppeition. The front endhf the bese -lQgis piroportion '14 "through I a sight openin end of the locking member 22.

wall ofthe tubular portion 14 and projecting into the groove 16 is the screw 18, the purpose of which is to provide a limiting stop to co-act with the screw 17 to limit the upward movement of the supporting rod 15.

The downward movement of the supporting rod 15 is limited by the base 19 of the supportingrod 15 striking against the upper edge of the tubular portion 14. Formed integral with and at the upper end of the supporting rod 15 is the cylindrical housing 20. The cylindrical housing 20 forms the body of the locking device,'is provided with V 20', and has threaded centrally thereof t e hollow shaft21. A looking member 22 may be secured ii -closed position by means of any suitable lock. In the construction as shown, the locking mem- 'ber 22 is provided with the aim 23 which,

when the device isin locked position, extends into the hollow shaft 21 centrally of the housing 20 and is held in position by means of a combination locking device. On the top of the arm 23, and spaced relative to each other are the locking lugs 24.

The index rings 25 have their outer peripheries divided into ten equal arts 26. Each part 26 is separated by a sma l indentation 27, and is marked from 0 to 9. On the inner peripheries of the index rings 25 are slots 28 for the various settings placed directly under each numeral on the ,outer periphery. The locking rings 29 are made to fit inside of the index rings 25, and on their inner peripheries are formed shoulders 30, which extend part way acrossand retain the locking lugs 24 of the arm 23 of the lockinggmember 22 when in locked position. The shoulders 30 have at a point in their circumference grooves 31, for the passage of the locking lugs 24 when bein withdrawn. From the outer periphery o the locking rings 29 project the pins 32 which fit into any of the slots 28 on the inner peripheries of the index rings 25. By inserting these ins'32 into different slots 28, different cominations of the lock may be made.

Extending upwardly from the cylindrical housing 20, and s acedrelative to each other are the two para lel arms 33 and 34. Pivotallymountc'd on the upper end of the arm 33 is the latch 35 which, when thedevice is in locked position, bridges the space between the arms 33 and 34, as shown in Figure 4, and is, designed to, enclose therein a s oke of the steering wheel 3 and the contro levers 5, as shown in Figure 1. The free end of the latch 35 is provided with a tongue36 adapted to enter the aperture 37 in the upper The locking member 22 at its lower extremity is shaped in the form of a disk 38 fromfwh-ich extends a pin 39. Thus it will be seen that when the locking member 22 is properly seated and secured in the recess 40 of the arm 34, the pin 39 extends into the apeiture"41 in the upper end of the base arm 12, while at the same time the tongue 36 of the latch member 35 is secured in the aperture 37. Thus it will be seen that the locking member performs two locking functions: (1) The retention of the supporting post 15, the cylindr1 cal housing 20, and the parallel locking arms and 34 in their elevated position with the spoke'of the steering wheel 3 and the control levers 5 confined therebetween, by means of the pin 39 engaging in the aperture 41. (2) The latch 35, being confined as before described, the spoke of the steeringwheel 3 and the control levers 5 are held completely en circled. The lockingmember 22 is provided with a knob 42 for the convenient withdrawal of the same from its locked position.

The knob 43 is made fast to the cylindrical housing 20 by means of the pin 44, and is adapted to receive the hook 45 of the clutch locking rod 46. From theupper portion 47 of the clutch locking rod 46 extends the threaded rod 48 enclosed by the sleeve 49. From the lower portion 50, extends the hol low rod 51, which is threaded on the inside into which is screwed the threaded rod 480 i the upper portion 47. By screwing the threaded rod 48 further into the hollow rod.

51, adjustment for length of the clutch look.

ing rod 46 may be made, The'clutch pedal lock 52 is hinged to the clutch locking rod 46, and by hearing evenly. onfthe bottom of the clutch pedal top revents the clutch pedal from being us down and the clutch from beinglt rown'out. When the lock is in its lowered 'sition, theclutch locking rod 46 may be isengage'd from the knob 43, and the clutch" edal lock 52 lowered to the floor, out of t e way of the -op eration of the clutch 2., The clutch locking rod'46 may be inserted in the spring clamp 53 and thus be held'in place out of the way of the driver. l i

Havin the lock installed on the steel-in post :of t e automobile directly in front of the chauffeur and-beneath the steering wheel, to lock the car, set the desired-combination on the combination rings, or unlock the look if other type is useldfmake sure that the clutch locking rod 46 is attached to the clutch locking rod knob 43, throw open the latch 35 and pull up the cylindrical housing 20 on the base 10 until it stops, catchin one of the spokes of the st ering wheel- 3 an the centrol levers 5 betwegnthe arms 33 and 34. Throw over the latch )35. Push in the look ing member 22 catching the. tongue '36 of the latch in the aperture 37 and pushing the pin 39 into the aperture '41 in the base arm 12.-

As the desired combination is set on the indcx ings 25, the locking lugs 24 on the arm 23 of the locking member 22 pass freely through the grooves 31 of the shoulders 30 of the locking rings 29. Then turn one or more of the index rings 25 locking the combination lock. The movement of the index rings 25 in turn moves the locking rings 29 as the pins 32 of the locking rings 29 lit into the slots 28 in the inner peripheries of the index rings 25. This moves the grooves 31 of the locking rings 29 out of alignment with each other and away from the locking lugs 24 on the arm 23, and the shoulders 30-. on the inner periphery of the locking rings 29 now extend across the ath of the locking lugs 24 and retain the loc ing member 22 in locked position. Lock in the usual manner t other type of lock is used. To unlock: Turn the index rings 25 until the desired reading of numbers is visible through the sight opening 20', the locking lugs 24 are now free to pass through the grooves 31 in the locking rings 29, or unlock the look if other type is used, and by means of the knob 42, pull out the looking member 22 which allows the latch 35 to open up and the encharacter described, firmly attached to the automobile, having arms extending upwardly therefrom and a" clutchlocking extension attached thereto, so arranged and adapted that when raised to'a locked posi- .tion, the arms engage a spoke of the steermg wheel and the clutch locking extension engages the clutch lever and retainsvit "inw'a locked position.
